Cloud providers can be organized in associations of multiple clouds with the objective of achieving all canonical properties expected from the cloud computing paradigm. However, problems inherent to the resource offering and consumption arise as one limitation to furnish cloud computing at its full extent. This work describes a multiple cloud architecture that utilizes a tournament model to promote...
Currently a predominant need for organizations is the support service that can provide its customers and partners, this assistance is an issue of great importance for the value involving customers and pays off in image for the organization. Thus the investment to sustain this service you get to become significant figures that could be saved by implementing Agents Assistance (AA) based software, which...
Context: Agile Governance has been suggested as an innovative approach based on the use of the principles and values of the manifesto for agile software development on traditional Governance. However, the evaluation of this maturity is presented as a challenge today. Objective: This article describes a proposal of a model for the evaluation of maturity according to the meta principles of Agile Governance...
In these days one of the most recurrent problem of the EA projects, is the elaboration of a roadmap that includes the set of initiatives, that close the gaps between an initial architecture (AS-IS) and a target architecture (TO-BE). The trouble of this task, is mostly because the choice of the transition plan that composes a roadmap, is made regardless the set of criteria and needs exposed by the...
Our work presents an approach to automatic detection of potentially redundant elements within an Enterprise Architecture (EA). Unintended or unidentified redundancies can affect the data quality, duplicating efforts which may lead to inconsistencies. Evaluating and identifying manually redundant elements in large information systems (IS) is a tedious, error-prone and time-consuming task. Untimely,...
Aspect-Orientated approach was created to solve scattering and tangling issues generated by the implementation of crosscutting requirements in programming. This approach has been proposed in many research areas regarding the entire process of software development, from requirements and business process models to code generating. Enterprise Architecture (EA) allows structural organization of artifacts...
In throughput-aware CMPs like GPUs and DSPs, software-managed streaming memory systems are an effective way to tolerate high latencies. E.g., the Cell/B.E. incorporates local memories, and data transfers to/from those memories are overlapped with computation using DMAs. In such designs, the latency of the memory system has little impact on performance; instead, memory bandwidth becomes critical. With...
Software product line engineering has emerged as one of the dominant paradigms for developing variety of software products based on a shared platform and shared software artifacts. An important and challenging type of software maintenance and evolution is how to cost-effectively manage the migration of legacy systems towards product lines. This paper presents a structured migration method and describes...
A system of systems (SoS) is formed from existing independent component systems. Some reasons these independent systems might be combined include a merger or acquisition, a temporary partnership, because of the formation of an integrated supply chain, or if a service-oriented architecture is used. SoSs are difficult to analyze because of the scale of the integration, the components’ independent existence,...
As ubiquitous virtual reality (U-VR) systems become more and more popular and several systems coexist all together, sharing events between them in order to improve the user experience and increase their scope and functionality will be mandatory. Since U-VR systems have a dynamic and decoupled nature, and they have their own event model, we propose in this paper a semantic publish/subscribe infrastructure...
Thanks to the attractions of the multimedia, namely interactivity and multimodality, it seems that web sites and CD-ROMs have the capacity to transmit heritage information to the public. But ultimately they miss real cognitive or educational purposes. Consequently, this article suggests enriching the conception of educational products, combining the potential of video games with the methods of representation...
Like RM-ODP [1], enterprise architecture (or EA for short) has its own perspectives as a basic construct for its architecture definition to represent areas of concern. In this paper, difference between RM-ODP and one concrete example EA, and applicability of Use of UML for ODP system specifications [2] (or UML4ODP in short) standard to the example EA, are discussed. Several additional diagrams that...
The UNICORE grid system provides a seamless, secure and intuitive access to distributed grid resources. In recent years, UNICORE 5 is used as a well-tested grid middleware system in production grids (e.g. DEISA, D-Grid) and at many supercomputer centers world-wide. Beyond this production usage, UNICORE serves as a solid basis in many European and International research projects and business scenarios...
In the current globalized world, characterized by strong Web based interactions, relationships between people and organizations are subject to fast changes. This situation justifies the need for an approach that can capture business changes and quickly implement them into computational systems. Considering that some business logic portions are quite volatile and susceptible to changes and other portions...
Requirements modeling has been recently introduced in the UML world with the form of a new profile called SysML. This paper explores the possibility to link concepts used to describe requirements with those of the enterprise language of RM-ODP. Some correspondence rules are proposed and illustrated on a case study.
The Open Distributed Processing Reference Model (ODP-RM) provides viewpoints and abstract infrastructure guidelines that can be used for a basis for enterprise architecture, especially for an inter-enterprise architecture. The ODP-RM does not prescribe methodology for modeling itself, but provides common vocabulary and focus for description. This paper performs a brief analysis of the ODP-RM (and...
An important issue to the adoption of any enterprise architectural approach is the availability of tools to support the development, storage, presentation, analysis, improvement and evolution of enterprise architecture representations. As with enterprise architecture methodologies, enterprise architecture tools to support the architectural development process are still emerging. Most important software...
